摘　　要：通过自组装聚合法工艺,利用聚吡咯对黏胶织物进行导电整理,并利用扫描电镜、红外光谱等表征导电织物的性能。测试表明,掺杂剂聚对苯乙烯磺酸钠的引入提高了聚吡咯的分散性能,且聚吡咯复合颗粒的粒径呈单峰分布,粒径尺寸主要集中在156μm左右。黏胶织物上的聚吡咯负载量、电导率与断裂强力均随着自组装层数的增加而增大;但当自组装层数超过6层时,各种指标变化速率下降。电导率和断裂强力均与黏胶织物上的聚吡咯负载量呈正相关变化。整理后的导电黏胶织物在自然状态下的导电性能较为稳定,在水中聚吡咯容易被水解而流失,致使电导率下降。综合分析认为:利用自组装聚合法制备导电织物具有很好的可行性。The conductive finishing of viscose fabric is carried out by self-assembly polymerization, and the properties of conductive fabric are characterized by scanning electron microscopy and infrared spectroscopy. The test shows that the introduction of dopant sodium polyphenylene sulfonate improves the dispersion performance of polypyrrole, and the particle size of polypyrrole composite particles is unimodal distribution, with the particle size mainly concentrated at 156 μ M or so. The load, conductivity and breaking strength of polypyrrole on viscose fabric increase with the increase of the number of self-assembled layers;However, when the number of self-assembled layers exceeds 6, the change rate of various indicators decreases. Conductivity and breaking strength are positively correlated with the load of polypyrrole on viscose fabric. The conductivity of the finished conductive viscose fabric is relatively stable in natural state, and polypyrrole is easy to be hydrolyzed in water and lost, resulting in a decrease in conductivity. Comprehensive analysis shows that it is feasible to prepare conductive fabrics by self-assembly polymerization.
